Replying to Back injury

so i was skiing a week ago and did an accidental front flip after getting my ski caught on a tire and did a front flip.  I landed on my back, and pulled a muscle; at least i thought a pulled a muscle.  A week later it is still really hurting me, and when I touch it screams with pain, but my movement seems normal, and is no longer limited like it was.
    My question to you guys is have you ever had a back injury and if so what?  how long does it take to get better?  I think my muscle is pulled, but it could possibly be my spine?  its the left side of my back muscle - not my lat muscle.    anyone ?
